Re: [CampusManager] Problems with XP

At least I'm not the only one having this problem, only thing is.... the
bridging (ie culprit laptop) takes down our network... The incident has
happened about 3-4 time since XP has been out on the market. There is a
ways where you can override the bridging manually . If interested here is
the whitepaper:
http://support.microsoft.com/default.aspx?scid=kb;en-us;283429&Product=winxp
KB: Article # 283429 Overall, I think Microsoft made a huge mistake
in this feature...but that is my opinion : )

Rick, Are you guys working on a solution if a bridging machine is detected
on the network, and is then cut off from the network? This would be a god
send if you create this feature.

thanks!
